OK, I see what your getting at now. In that case, it certanly could be
requested as an enhancement, but I wouldn't say that it is a bug because
it was never a feature of the utility i.e. it was developed for strings
rather than symbols. However, at what point do we draw the line. For
example, should the symbol 'buffer be added to put a \b at each end etc.

Personally, I can't see where I'd have a use for this feature. this
doesn't mean there isn't a use case, I have just never come across
one. On the other hand, I've used regexp-opt for matching against
strings a lot.
